Amphenol Corp. reported an insider ownership change involving Walter Luc in a Form 4 filed on May 27, 2026, covering a transaction date of May 22, 2026. The filing concerns Amphenol’s Class A Common Stock. The document indicates that Luc had a reportable ownership change, but the provided filing text does not include the transaction table normally used to show the exact transaction code, number of shares or derivative securities involved, transaction price, or Luc’s beneficial ownership following the transaction. As a result, the filing excerpt does not make clear whether the action was an acquisition, disposition, option exercise, grant, vesting event, or another reportable insider transaction. The filing does include an explanatory note on exercisability: the relevant security becomes exercisable at a rate of 20% per year over five years, beginning on the first anniversary of the grant date. That language is typical of employee stock options or similar derivative securities granted under an equity compensation plan, suggesting the reported item may relate to an option or other award with a staged vesting schedule. The Form 4 was signed on Luc’s behalf by Lance E. D’Amico under power of attorney on May 27, 2026. While the filing confirms a reportable insider ownership event tied to Amphenol Class A Common Stock on May 22, the excerpt lacks the key numerical details—share count, price, transaction code, and post-transaction holdings—needed to assess the size or economic impact of the action.
